Synthesis of 3-Benzoylcyclohexanone, A key Intermediate for the Synthesis of Ketoprofen

Abstract
A simple and convenient synthesis of 3-benzoylcyclohexanone, a ketoprofen precursor, is proposed. It consists of the preparation of 5-trimethylsilyl-3-cyclohexenone via disilylation of anisole followed by hydrolysis and subsequent regiospecific benzoylation and hydrogenation.
